Most of the information easily available on the internet speaks of the Ainu in the past tense: The Ainu were hunter-gatherers; the Ainu worshiped; the Ainu were conquered. The photographic situation is similar: an image search for “Ainu” brings up a few dozen century-old photos and not much else.
But the modern Ainu, of course, do not live in the past–they live in today, primarily in the very modern city of Sapporo. The modern Ainu are not hunter-gatherers (although the entire nation of Japan remains highly dependent on fishing for its nutrition;) they are doctors and shop-keepers, office workers and artists. They go to school, keep up with modern fashions, play video games, and ride the shinkansen just like everyone else in Japan.
Wikipedia (and everyone else) estimates that about 25,000 Ainu live today in Japan, with the caveat that since the Ainu don’t always bother to mention their ancestry, there could be a couple hundred thousand who just haven’t been counted.
Due to years of inter-marrying, the vast majority of today’s Ainu are at least part Japanese. One reference I recall estimated that about 300 pure-blooded Ainu remained in 1950; another estimated that 200 remain today.
There are also some Ainu living in Russia; according to Wikipedia, about 100 Russians tried to identify as Ainu in the 2010 census, and nearly a thousand people with some degree of Ainu ancestry live in the area.
Alas for my purposes as a writer, these few remaining folks appear to be living their lives out in anthropological anonymity, rather than posting selfies tagged #RealAinu all over the internet.
The one thing everyone likes to argue about in threads about the Ainu is whether or not they look like white people.
It’s kind of dumb to fight about, since obviously Ainu look like Ainu.
Okay, okay. Don’t start a flame war. According to Wikipedia:
Turner found remains of Jōmon people of Japan to belong to Sundadont pattern similar with the Southern Mongoloid living populations of Taiwanese aborigines, Filipinos, Indonesians, Thais, Borneans, Laotians, and Malaysians. …
Your Y-haplogroup traces your paternal ancestry, because men (and only men) inherit their Y-chromosomes from their fathers. Your M or Mt-DNA, (short for mitochondrial DNA,) hails exclusively from your mother (and both men and women have Mt-DNA, because we all have mitochondria.)
Often when one group of people conquers another group of people, their descendants end up with Y-DNA from the conquerors and MtDNA from the conquered, but there are other ways people come together, like folks intermarrying with their neighbors.
(Presumably this study was done with relatively pure-blooded Ainu.)
The distribution of Haplogroup D-M174 is quite suggestive: Ainu, Tibetans, and Andaman Islanders. These are three (historically) highly isolated groups–one of the world’s few remaining basically uncontacted peoples, the Sentinelese, (they’ll put a spear in you if you land on their island) live in the Andaman Islands. The Tibetans, as I’ve mentioned, have inherited DNA from the Denisovans–cousins of the Neanderthals who interbred with their ancestors–that lets them breathe more easily at high altitudes than anyone else on Earth, making it rather hard for non-Tibetans move there, much less conquer and occupy it [Note: I wouldn’t be surprised if the Nepalese or other folks who also live up in the Himalayas also have the adaptation; this isn’t meant to be a discussion of modern political borders.] And the Ainu basically live on the far edge of Asian at the southern edge of Siberia–northern Japan is the snowiest populated place in the world.
“Sinodont” and “sundadont” actually refer to two different tooth shapes.
Tibetans and Andaman Islanders are definitely Asians–they clade with other Asians in the Greater Asian Clade–but they don’t look much alike. You wouldn’t mistake them for Caucasians, though.
Haplogroup D-M174 is believed to have evolved about 50-60-thousand years ago, presumably in Asia. This was shortly after the Out-of-Africa event, which occurred about 70,000 (or possibly 100,000 years ago [there might have been more than one OOA.]) D-M174 is so old that its “parent” haplogroup is DE, which is found in Africa and Asia.
By contrast, the mutation to the EDAR-gene which gives Han Chinese (the Asian ethnic group Americans are most familiar with) and Japanese their characteristic hair, skin, tooth shape, build, etc., (EDAR is pretty incredible in that way) only occurred 30,000 years ago–that is, the Ainu split off from other Asians 20-30 thousand years before what we think of as “the Asian look” had even evolved.
For that matter, Caucasian themselves only appear to have split off from Asians around 40,000 years ago–10,000 years before EDAR mutated, but 10-20,000 years after D-M174 arose.
Or to put it another way:
About 70,000 years ago, an intrepid band of explorers left Africa. Presumably, these people looked African, but I don’t know exactly which Africans these ancient people looked like–perhaps they didn’t really look like any modern group; perhaps they looked a lot like most Sub-Saharan Africans; perhaps they looked like the Bushmen, noted for their tawny skin tones and more “Asian” look than other Sub-Saharans. I don’t know yet.
About 60,000 years ago, the band split, and one group spread far across Asia. Their modern descendants are the Ainu, Tibetans, and Andaman Islanders.
The other group presumably hung out in central Eurasia, until about 40,000 years ago, when it definitively split. One group went west and became the Caucasians; the other became the Han.
Around 30,000 years, the distinctive EDAR mutation that gives east-Asians their “typical” appearance evolved.
Around 10,000 years ago, more or less, Europeans began getting lighter, and “whiteness” as we know it evolved.
So… could the Ainu retain some traits or have never obtained some traits–like epicanthic folds at the corners of their eyes–which make them look more like their ancestral group, to which the ancestors of both Asians and Caucasians belonged? Sure. Could they have just evolved traits to deal with the extremely cold, near-Siberian environment they lived in that happened to resemble traits that evolved in European populations dealing with a similarly cold environment? Sure.
But are they Caucasians? Not even remotely.
And in my opinion, they don’t look Caucasian, at least not when their faces aren’t covered with big, bushy beards. (The modern Ainu tend to shave.) Take, for example, Oki Kano, an Ainu musician. Nothing about his appearance says, “Mysterious tribe of lost Caucasians.”
Back to Wikipedia:
In a study by Tajima et al. (2004), two out of a sample of sixteen (or 12.5%) Ainu men have been found to belong to Haplogroup C-M217, which is the most common Y-chromosome haplogroup among the indigenous populations of Siberia and Mongolia. … Some researchers have speculated that this minority of Haplogroup C-M217 carriers among the Ainu may reflect a certain degree of unidirectional genetic influence from the Nivkhs, a traditionally nomadic people of northern Sakhalin and the adjacent mainland, with whom the Ainu have long-standing cultural interactions.
The Nivkhs live basically next door and have a lot of cultural similarities–for example, both groups traditionally had shamanic rituals involving bears, which they raised and then sacrificed:
Nivkh Shamans also presided over the Bear Festival, a traditional holiday celebrated between January and February depending on the clan. Bears were captured and raised in a corral for several years by local women, treating the bear like a child. The bear was considered a sacred earthly manifestation of Nivkh ancestors and the gods in bear form (see Bear worship). During the Festival, the bear would be dressed in a specially made ceremonial costume. It would be offered a banquet to take back to the realm of gods to show benevolence upon the clans. After the banquet, the bear would be sacrificed and eaten in an elaborate religious ceremony. Often dogs were sacrificed as well. The bear’s spirit returned to the gods of the mountain ‘happy’ and would then reward the Nivkh with bountiful forests. …
While haplogroup D-M174 shows affinity with more southerly Asian groups, like the Tibetans or Andaman Islanders, haplogroup C-M217 is found throughout northern Asia (principally Siberia) and northern North America.
If everyone in the world exhibits a particular behavior, chances are it’s innate. But I have been informed–by Harvard-educated people, no less–that humans do not have instincts. We are so smart, you see, that we don’t need instincts anymore.
This is nonsense, of course.
One amusing and well-documented human instinct is the nesting instinct, experienced by pregnant women shortly before going into labor. (As my father put it, “When shes starts rearranging the furniture, get the ready to head to the hospital.”) Having personally experienced this sudden, overwhelming urge to CLEAN ALL THE THINGS multiple times, I can testify that it is a real phenomenon.
Humans have other instincts–babies will not only pick up and try to eat pretty much anything they run across, to every parent’s consternation, but they will also crawl right up to puddles and attempt to drink out of them.
But we’re getting ahead of ourselves: What, exactly, is an instinct? According to Wikipedia:
Instinct or innate behavior is the inherent inclination of a livingorganism towards a particular complex behavior. The simplest example of an instinctive behavior is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a clearly defined stimulus.
Any behavior is instinctive if it is performed without being based upon prior experience (that is, in the absence of learning), and is therefore an expression of innate biological factors. …
Instincts are inborn complex patterns of behavior that exist in most members of the species, and should be distinguished from reflexes, which are simple responses of an organism to a specific stimulus, such as the contraction of the pupil in response to bright light or the spasmodic movement of the lower leg when the knee is tapped.
The go-to example of an instinct is the gosling’s imprinting instinct. Typically, goslings imprint on their mothers, but a baby gosling doesn’t actually know what its mother is supposed to look like, and can accidentally imprint on other random objects, provided they are moving slowly around the nest around the time the gosling hatches.
Here we come to something I think may be useful for distinguishing an instinct from other behaviors: an instinct, once triggered, tends to keep going even if it has been accidentally or incorrectly triggered. Goslings look like they have an instinct to follow their mothers, but they actually have an instinct to imprint on the first large, slowly moving object near their nest when they hatch.
So if you find people strangely compelled to do something that makes no sense but which everyone else seems to think makes perfect sense, you may be dealing with an instinct. For example, women enjoy celebrity gossip because humans have an instinct to keep track of social ranks and dynamics within their own tribe; men enjoy watching other men play sports because it conveys the vicarious feeling of defeating a neighboring tribe at war.
So what about racism? Is it an instinct?
Strictly speaking–and I know I have to define racism, just a moment–I don’t see how we could have evolved such an instinct. Races exist because major human groups were geographically separated for thousands of years–prior to 1492, the average person never even met a person of another race in their entire life. So how could we evolve an instinct in response to something our ancestors never encountered?
Unfortunately, “racism” is a chimera, always changing whenever we attempt to pin it down, but the Urban Dictionary gives a reasonable definition:
An irrational bias towards members of a racial background. The bias can be positive (e.g. one race can prefer the company of its own race or even another) or it can be negative (e.g. one race can hate another). To qualify as racism, the bias must be irrational. That is, it cannot have a factual basis for preference.
Of course, instincts exist because they ensured our ancestors’ survival, so if racism is an instinct, it can’t exactly be “irrational.” We might call a gosling who follows a scientist instead of its mother “irrational,” but this is a misunderstanding of the gosling’s motivation. Since “racist” is a term of moral judgment, people are prone to defending their actions/beliefs towards others on the grounds that it can’t possibly be immoral to believe something that is actually true.
The claim that people are “racist” against members of other races implies, in converse, that they exhibit no similar behaviors toward members of their own race. But even the most perfunctory overview of history reveals people acting in extremely “racist” ways toward members of their own race. During the Anglo-Boer wars, the English committed genocide against the Dutch South Africans (Afrikaners.) During WWII, Germans allied with the the Japanese and slaughtered their neighbors, Poles and Jews. (Ashkenazim are genetically Caucasian and half Italian.) If Hitler were really racist, he’d have teamed up with Stalin and Einstein–his fellow whites–and dropped atomic bombs on Hiroshima. (And for their part, the Japanese would have allied with the Chinese against the Germans.)
The murder victim, a West African chimpanzee called Foudouko, had been beaten with rocks and sticks, stomped on and then cannibalised by his own community. …
“When you reverse that and have almost two males per every female — that really intensifies the competition for reproduction. That seems to be a key factor here,” says Wilson.
Jill Pruetz at Iowa State University, who has been studying this group of chimpanzees in south-eastern Senegal since 2001, agrees. She suggests that human influence may have caused this skewed gender ratio that is likely to have been behind this attack. In Senegal, female chimpanzees are poached to provide infants for the pet trade. …
Early one morning, Pruetz and her team heard loud screams and hoots from the chimps’ nearby sleep nest. At dawn, they found Foudouko dead, bleeding profusely from a bite to his right foot. He also had a large gash in his back and a ripped anus. Later he was found to have cracked ribs. Pruetz says Foudouko probably died of internal injuries or bled out from his foot wound.
Foudouko also had wounds on his fingers. These were likely to have been caused by chimps clamping them in their teeth to stretch his arms out and hold him down during the attack, says Pruetz.
After his death, the gang continued to abuse Foudouko’s body, throwing rocks and poking it with sticks, breaking its limbs, biting it and eventually eating some of the flesh.
“It was striking. The female that cannibalised the body the most, she’s the mother of the top two high-ranking males. Her sons were the only ones that really didn’t attack the body aggressively,” Pruetz says …
Historically, the vast majority of wars and genocides were waged by one group of people against their neighbors–people they were likely to be closely related to in the grand scheme of things–not against distant peoples they’d never met. If you’re a chimp, the chimp most likely to steal your banana is the one standing right in front of you, not some strange chimp you’ve never met before who lives in another forest.
Indeed, in Jane Goodall’s account of the Gombe Chimpanzee War, the combatants were not members of two unrelated communities that had recently encountered each other, but members of a single community that had split in two. Chimps who had formerly lived peacefully together, groomed each other, shared bananas, etc., now bashed each other’s brains out and cannibalized their young. Poor Jane was traumatized.
I think there is an instinct to form in-groups and out-groups. People often have multiple defined in-groups (“I am a progressive, a Christian, a baker, and a Swede,”) but one of these identities generally trumps the others in importance. Ethnicity and gender are major groups most people seem to have, but I don’t see a lot of evidence suggesting that the grouping of “race” is uniquely special, globally, in people’s ideas of in- and out-.
For example, as I am writing today, people are concerned that Donald Trump is enacting racist policies toward Muslims, even though “Muslim” is not a race and most of the countries targeted by Trump’s travel/immigration ban are filled with fellow Caucasians, not Sub-Saharan Africans or Asians.
Race is a largely American obsession, because our nation (like the other North and South American nations,) has always had whites, blacks, and Asians (Native Americans). But many countries don’t have this arrangement. Certainly Ireland didn’t have an historical black community, nor Japan a white one. Irish identity was formed in contrast to English identity; Japanese in contrast to Chinese and Korean.
Only in the context where different races live in close proximity to each other does it seem that people develop strong racial identities; otherwise people don’t think much about race.
Napoleon Chagnon, a white man, has spent years living among the Yanomamo, one of the world’s most murderous tribes, folks who go and slaughter their neighbors and neighbors’ children all the time, and they still haven’t murdered him.
Why do people insist on claiming that Trump’s “Muslim ban” is racist when Muslims aren’t a race? Because Islam is an identity group that appears to function similarly to race, even though Muslims come in white, black, and Asian.
If you’ve read any of the comments on my old post about Turkic DNA, Turkey: Not very Turkic, you’ll have noted that Turks are quite passionate about their Turkic identity, even though “Turkic” clearly doesn’t correspond to any particular ethnic groups. (It’s even more mixed up than Jewish, and that’s a pretty mixed up one after thousands of years of inter-breeding with non-Jews.)
Group identities are fluid. When threatened, groups merged. When resources are abundant and times are good, groups split.
What about evidence that infants identify–stare longer at–faces of people of different races than their parents? This may be true, but all it really tells us is that babies are attuned to novelty. It certainly doesn’t tell us that babies are racist just because they find people interesting who look different from the people they’re used to.
What happens when people encounter others of a different race for the first time?
We have many accounts of “first contacts” between different races during the Age of Exploration. For example, when escaped English convict William Buckley wandered into an uncontacted Aborigine tribe, they assumed he was a ghost, adopted him, taught him to survive, and protected him for 30 years. By contrast, the last guy who landed on North Sentinel Island and tried to chat with the natives there got a spear to the chest and a shallow grave for his efforts. (But I am not certain the North Sentinelese haven’t encountered outsiders at some point.)
But what about the lunchroom seating habits of the wild American teenager?
If people have an instinct to form in-groups and out-groups, then races (or religions?) may represent the furthest bounds of this, at least until we encounter aliens. All else held equal, perhaps we are most inclined to like the people most like ourselves, and least inclined to like the people least like ourselves–racism would thus be the strongest manifestation of this broader instinct. But what about people who have a great dislike for one race, but seem just fine with another, eg, a white person who likes Asians but not blacks, or a black who like Asians but not whites? And can we say–per our definition above–that these preferences are irrational, or are they born of some lived experience of positive or negative interactions?
Again, we are only likely to have strong opinions about members of other races if we are in direct conflict or competition with them. Most of the time, people are in competition with their neighbors, not people on the other side of the world. I certainly don’t sit here thinking negative thoughts about Pygmies or Aborigines, even though we are very genetically distant from each other, and I doubt they spend their free time thinking negatively about me.
Just because flamingos prefer to flock with other flamingos doesn’t mean they dislike horses; for the most part, I think people are largely indifferent to folks outside their own lives.
A recent article in Stanford Magazine highlighted the work of psychologist Richard Lampiere. Back in 1931, Lampiere, a Chinese student of his, and his student’s Chinese wife drove cross-country, visiting 250 hotels and restaurants.
One business refused them service, presumably because of race.
Then Lampiere sent surveys to the businesses they’d visited (plus controls) asking if they served Chinese people. The businesses responded:
235 said NO,
18 said maybe,
and only 2 said YES.
Basically the complete opposite of reality.
Social signalling is cheap; losing actual customers on the ground is expensive.
People today still say whatever they think will gain them approval, though our politics have changed a lot since 1931. For example, 89% of people these days report being willing to marry someone of another race:
but of marriages conducted in 2013, only 12% actually were. By contrast, while a similar number of people said they would be unhappy about a cross-political marriage in their family:
In Hunters, Pastoralists, and Ranchers: Reindeer Economies and their Transformations [PDF,] Ingold describes the social distribution of food among hunter-gatherers. In normal times, when food is neither super-abundant nor scarce, each family basically consumes what it brings in, without feeling any particular compulsion to share with their neighbors. In times of super-abundance, food is distributed throughout the tribe, often quite freely:
Since harvested animals, unlike a plant crop, will not reproduce, the multiplicative accumulation of material wealth is not possible within the framework of hunting relations of production. Indeed, what is most characteristic of hunting societies everywhere is the emphasis not on accumulation but on its obverse: the sharing of the kill, to varying degrees, amongst all those associated with the hunter. …
The fortunate hunter, when he returns to camp with his kill, is expected to play host to the rest of the community, in bouts of extravagant consumption.
The other two ethnographies I have read of hunter-gatherers (The Harmless People, about the Bushmen of the Kalahari, and Kabloona, about the Eskimo aka Inuit) both support this: large kills are communal feasts. Hunter gatherers often have quite strict rules about how exactly a kill is to be divided, but the most important thing is that everyone gets some.
And this is eminently sensible–you try eating an entire giraffe by yourself, in the desert, before it rots.
Even in the arctic, where men can (in part of the year) freeze food for the future, your neighbor’s belly is as good as a freezer, because the neighbor you feed today will feed you tomorrow. Hunting is an activity that can be wildly successful one day and fail completely the next, so if hunters did not share with each other, soon each one would starve.
Whilst the successful hunter is required to distribute his spoils freely amongst his camp fellows, he does so with the assurance that in any future eventuality, when through bad luck he fails to find game, or through illness or old age he can no longer provide for himself and his family, he will receive in his turn. Were each hunter to produce only for his own domestic needs, everyone would eventually perish from hunger (Jochelson 1926:124). Thus, through its contribution to the survival and reproduction of potential producers, sharing ensures the perpetuation of society as a whole. …
Yet he is also concerned to set aside stocks of food to see his household through at least a part of the coming winter. The meat that remains after the obligatory festive redistribution is therefore placed in the household’s cache, on which the housewife can draw specifically for the provision of her own domestic group (Spencer 1959:149). After the herds have passed by, domestic autonomy is re-establisheddraws on its own reserves of stored food.
But what happens at the opposite extreme, not under conditions of abundance, but when everyone‘s stocks run out? Ingold claims that in times of famine, the obligation to share what little food one has with one’s neighbors is also invoked:
We find, therefore, that the incidence of generalized reciprocity tends to peak towards the two extremes of scarcity and abundance… The communal feast that follows a successful hunting drive involves the same heightening of band solidarity, and calls into play the same functions of leadership in the apportionment of food, as does the consumption of famine rations.
I am reminded here of a scene in The Harmless People in which there was not enough food to go around, but the rules of distribution were still followed, each person just cutting their piece smaller. Thomas described one of the small children, hungry, trying to grab the food bowl–not the food itself–to stop their mother from giving away their food to the next person in the chain of obligation.
Here Ingold pauses to discuss a claim by Sahlins that such social order will (or should) break down under conditions of extreme hunger:
Probably every primitive organization has its breaking-point, or at least its turning-point. Every one might see the time when co-operation is overwhelmed by the scale of disaster and chicanery becomes the order of the day. The range of assistance contracts progressively to the family level; perhaps even these bonds dissolve and, washed away, reveal an inhuman, yet most human, self-interest. Moreover, by the same measure that the circle of charity is
compressed that of ‘negative reciprocity* is potentially expanded. People who helped each other in normal times and through the first stages of disaster display now an indifference to each others’ plight, if they do not exacerbate a mutual downfall by guile, haggle and theft.
I can find no evidence, either in my reading of circumpolar ethnography, or in the material cited by Sahlins, for the existence of such a ‘turning-point’ in hunting societies. On the contrary, as the crisis deepens, generalized reciprocity proceeds to the point of dissolution of domestic group boundaries. ‘Negative reciprocity’, rather than closing in from beyond the frontiers of the household, will be expelled altogether from the wider social field, only to make its appearance within the heart of the domestic group itself.
Thus the women of the household, who are allowed to eat only after the appetites of their menfolk have been satisfied, may be left in times of want with the merest scraps of food. Among the Chipewyan, ‘when real distress approaches, many of them are permitted to starve, when the males are amply provided for’…
In situations of economic collapse, negative reciprocity afflicts not only the domestic relations between husband and wife, but those between mother and child, and between parent and grandparent. If the suckling of children is the purest expression of generalized reciprocity, in the form of a sustained one-way flow, then infanticide must surely represent the negative extreme. Likewise, old or sick members of the household will be the first to be abandoned when provisions run short. Even in normal times, individuals who are past labour have to scavenge the left-overs of food and skins (Hearne 1911:326). In the most dire circumstances of all, men will consume their starving wives and children before turning upon one another.
Drawing on Eskimo material, Hoebel derives the following precepts of cannibal conduct: Not unusually . . . parents kill their own children to be eaten. This act is no different from infanticide. A man may kill and eat his wife; it is his privilege. Killing and eating a relative will produce no legal consequences. It is to be presumed, however, that killing a non-relative for food is murder. (1941:672, cited in Eidlitz 1969:132)
In short, the ‘circle of charity’ is not compressed but inverted: as the threat of starvation becomes a reality, the legitimacy of killing increases towards the centre. The act is ‘inhuman’ since it strips the humanity of the victim to its organic, corporeal substance. If altruism is an index of sociability, then its absolute negation annuls the sodality of the recipient: persons, be they human or animal, become things.
This is gruesome, but let us assume it is true (I have not read the accounts Ingold cites, so I must trust him, and I do not always trust him but for now we will.)
The cold, hard logic of infanticide is that a mother can produce more children if she loses one, but a child who has lost its mother will likely die as well, along with all of its siblings. One of my great-great grandmothers suffered the loss of half her children in infancy and still managed to raise 5+ to adulthood. Look around: even with abortion and birth control widely available, humanity is not suffering a lack of children. ETA: As BaruchK correctly noted, today’s children are largely coming from people who don’t use birth control or have legal access to abortion; fertility rates are below replacement throughout the West, with the one exception AFAIK of Israel.
Furthermore, children starve faster and are easier to kill than parents; women are easier to kill than men; people who live with you are easier to kill than people who don’t.
“Finally, as the footsteps stopped just outside the igloo, it was the old man who went out to investigate.
“He emerged to see a disoriented figure seemingly unaware of his presence. The being was touching the outside of the igloo with curiosity, and raised no protest when the old man reached his hand out to touch its cheek.
“His skin was cold. …
The figures, of course, were the last survivors of the Franklin Expedition. They had buried their captain. They had seen their ship entombed by ice. They had eaten the dead to survive. …
Inuit nomads had come across streams of men that “didn’t seem to be right.” Maddened by scurvy, botulism or desperation, they were raving in a language the Inuit couldn’t understand. In one case, hunters came across two Franklin Expedition survivors who had been sleeping for days in the hollowed-out corpses of seals. …
The figures were too weak to be dangerous, so Inuit women tried to comfort the strangers by inviting them into their igloo. …
The men spit out pieces of cooked seal offered to them. They rejected offers of soup. They grabbed jealous hold of their belongings when the Inuit offered to trade.
When the Inuit men returned to the camp from their hunt, they constructed an igloo for the strangers, built them a fire and even outfitted the shelter with three whole seals. …
When a small party went back to the camp to retrieve [some items], they found an igloo filled with corpses.
The seals were untouched. Instead, the men had eaten each other. …
In 1854, Rae had just come back from a return trip to the Arctic, where he had been horrified to discover that many of his original Inuit sources had fallen to the same fates they had witnessed in the Franklin Expedition.
An outbreak of influenza had swept the area, likely sparked by the wave of Franklin searchers combing the Arctic. As social mores broke down, food ran short.
Inuit men that Rae had known personally had chosen suicide over watching the slow death of their children. Families had starved for days before eating their dog teams. Some women, who had seen their families die around them, had needed to turn to the “last resource” to survive the winter.
Infanticide, cannibalism, and human sacrifice were far more common prior to 1980 or so than we like to think; God forbid we should ever know such fates.
“Many Neolithic groups routinely resorted to infanticide … Joseph Birdsell believed that infanticide rates in prehistoric times were between 15% and 50% of the total number of births, while Laila Williamson estimated a lower rate ranging from 15% to 20%.:66… Comparative anthropologists have calculated that 50% of female newborn babies were killed by their parents during the Paleolithic era. Decapitated skeletons of hominid children have been found with evidence of cannibalism. …
“Three thousand bones of young children, with evidence of sacrificial rituals, have been found in Sardinia. Pelasgians offered a sacrifice of every tenth child during difficult times. Syrians sacrificed children to Jupiter and Juno. Many remains of children have been found in Gezer excavations with signs of sacrifice. Child skeletons with the marks of sacrifice have been found also in Egypt dating 950-720 BCE. In Carthage “[child] sacrifice in the ancient world reached its infamous zenith.”:324 …
“According to Shelby Brown, Carthaginians, descendants of the Phoenicians, sacrificed infants to their gods. Charred bones of hundreds of infants have been found in Carthaginian archaeological sites. One such area harbored as many as 20,000 burial urns. …
“… the exposure of newborns was widely practiced in ancient Greece, it was even advocated by Aristotle in the case of congenital deformity — “As to the exposure of children, let there be a law that no deformed child shall live.” …
“The practice was prevalent in ancient Rome, as well. … A letter from a Roman citizen to his sister, or a pregnant wife from her husband, dating from 1 BC, demonstrates the casual nature with which infanticide was often viewed:
“I am still in Alexandria. … I beg and plead with you to take care of our little child, and as soon as we receive wages, I will send them to you. In the meantime, if (good fortune to you!) you give birth, if it is a boy, let it live; if it is a girl, expose it.” 
“In some periods of Roman history it was traditional for a newborn to be brought to the pater familias, the family patriarch, who would then decide whether the child was to be kept and raised, or left to die by exposure. The Twelve Tables of Roman law obliged him to put to death a child that was visibly deformed. …
“Philosopher Han Fei Tzu, a member of the ruling aristocracy of the 3rd century BC, who developed a school of law, wrote: “As to children, a father and mother when they produce a boy congratulate one another, but when they produce a girl they put it to death.” …
“Buddhist belief in transmigration allowed poor residents of the country to kill their newborn children if they felt unable to care for them, hoping that they would be reborn in better circumstances. Furthermore, some Chinese did not consider newborn children fully “human”, and saw “life” beginning at some point after the sixth month after birth.
“Contemporary writers from the Song dynasty note that, in Hubei and Fujian provinces, residents would only keep three sons and two daughters (among poor farmers, two sons and one daughter), and kill all babies beyond that number at birth.”
“It was not uncommon that parents threw a child to the sharks in the Ganges River as a sacrificial offering. The British colonists were unable to outlaw the custom until the beginnings of the 19th century.:78
“According to social activists, female infanticide has remained a problem in India into the 21st century, with both NGOs and the government conducting awareness campaigns to combat it. …
“In the Eastern Shoshone there was a scarcity of Indian women as a result of female infanticide. For the MaiduNative Americans twins were so dangerous that they not only killed them, but the mother as well. In the region known today as southern Texas, the Mariame Indians practiced infanticide of females on a large scale. Wives had to be obtained from neighboring groups.”
In 2005 a mass grave of one- to two-year-old sacrificed children was found in the Maya region of Comalcalco. The sacrifices were apparently performed for consecration purposes when building temples at the Comalcalco acropolis. …
Archaeologists have found the remains of 42 children sacrificed to Tlaloc (and a few to Ehecátl Quetzalcóatl) in the offerings of the Great Pyramid of Tenochtitlan. In every case, the 42 children, mostly males aged around six, were suffering from serious cavities, abscesses or bone infections that would have been painful enough to make them cry continually. Tlaloc required the tears of the young so their tears would wet the earth. As a result, if children did not cry, the priests would sometimes tear off the children’s nails before the ritual sacrifice.
It is perhaps more profitable to ask which cultures didn’t practice some form of infanticide/infant sacrifice/cannibalism than which ones did. The major cases Wikipedia notes are Ancient Egypt, Judaism, Christianity, and Islam (we may note that Judaism in many ways derived from ancient Egypt, and Christianity and Islam from Judaism.) Ancient Egypt stands out as unique among major the pre-modern, pre-monotheistic societies to show no signs of regular infanticide–and even in the most infamous case where the Egyptian pharaoh went so far as to order the shocking act, we find direct disobedience in his own household:
3 And when she [Jochebed] could not longer hide him [the baby], she took for him an ark of bulrushes, and daubed it with slime and with pitch, and put the child therein; and she laid it in the flags by the river’s brink.4 And his sister stood afar off, to wit what would be done to him.
5 And the daughter of Pharaoh came down to wash herself at the river; and her maidens walked along by the river’s side; and when she saw the ark among the flags, she sent her maid to fetch it.
6 And when she had opened it, she saw the child: and, behold, the babe wept. And she had compassion on him, and said, “This is one of the Hebrews’ children.”
7 Then said his sister to Pharaoh’s daughter, “Shall I go and call to thee a nurse of the Hebrew women, that she may nurse the child for thee?”
8 And Pharaoh’s daughter said to her, “Go.” And the maid went and called the child’s mother.
9 And Pharaoh’s daughter said unto her, “Take this child away, and nurse it for me, and I will give thee thy wages.” And the women took the child, and nursed it.
10 And the child grew, and she brought him unto Pharaoh’s daughter, and he became her son. And she called his name Moses: and she said, “Because I drew him out of the water.”
I don’t know the actual infanticide numbers in modern Muslim countries (le wik notes that poverty in places like Pakistan still drives infanticide) but it is officially forbidden by Islam.
Today, between the spread of Abrahamic religions, Western Values, and general prosperity, the infanticide rate has been cut and human sacrifice and cannibalism have been all but eliminated. Abortion, though, is legal–if highly controversial–throughout the West and Israel.
According to the CDC, the abortion rate for 2013 was 200 abortions per 1,000 live births, or about 15% of pregnancies. (The CDC also notes that the abortion rate has been falling since at least 2004.) Of these, “91.6% of abortions were performed at ≤13 weeks’ gestation; … In 2013, 22.2% of all abortions were early medical abortions.”
To what can we attribute this anti-infanticide sentiment of modern monotheistic societies? Is it just a cultural accident, a result of inheritance from ancient Egypt, or perhaps the lucky effects of some random early theologian? Or as the religious would suggest, due to God’s divine decree? Or is it an effect of the efforts parents must expend on their few children in societies where children must attend years of school in order to succeed?
In ecology, r/K selection theory relates to the selection of combinations of traits in an organism that trade off between quantity and quality of offspring. The focus upon either increased quantity of offspring at the expense of individual parental investment of r-strategists, or reduced quantity of offspring with a corresponding increased parental investment of K-strategists, varies widely, seemingly to promote success in particular environments. …
where r is the maximum growth rate of the population (N), K is the carrying capacity of its local environmental setting, and the notation dN/dt stands for the derivative of N with respect to t (time). Thus, the equation relates the rate of change of the population N to the current population size and expresses the effect of the two parameters. …
As the name implies, r-selected species are those that place an emphasis on a high growth rate, and, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K). A typical r species is the dandelion Taraxacum genus.
In unstable or unpredictable environments, r-selection predominates due to the ability to reproduce quickly. There is little advantage in adaptations that permit successful competition with other organisms, because the environment is likely to change again. Among the traits that are thought to characterize r-selection are high fecundity, small body size, early maturity onset, short generation time, and the ability to disperse offspring widely. …
By contrast, K-selected species display traits associated with living at densities close to carrying capacity, and typically are strong competitors in such crowded niches that invest more heavily in fewer offspring, each of which has a relatively high probability of surviving to adulthood (i.e., low r, high K). In scientific literature, r-selected species are occasionally referred to as “opportunistic” whereas K-selected species are described as “equilibrium”.
In stable or predictable environments, K-selection predominates as the ability to compete successfully for limited resources is crucial and populations of K-selected organisms typically are very constant in number and close to the maximum that the environment can bear (unlike r-selected populations, where population sizes can change much more rapidly).
Traits that are thought to be characteristic of K-selection include large body size, long life expectancy, and the production of fewer offspring, which often require extensive parental care until they mature.
Rushton’s book Race, Evolution, and Behavior (1995) uses r/K selection theory to explain how East Asians consistently average high, blacks low, and whites in the middle on an evolutionary scale of characteristics indicative of nurturing behavior. He first published this theory in 1984. Rushton argues that East Asians and their descendants average a larger brain size, greater intelligence, more sexual restraint, slower rates of maturation, and greater law abidingness and social organization than do Europeans and their descendants, who average higher scores on these dimensions than Africans and their descendants. He theorizes that r/K selection theory explains these differences.
I’d be remiss if I didn’t also mention that the article states, “Rushton’s application of r/K selection theory to explain differences among racial groups has been widely criticised. One of his many critics is the evolutionary biologistJoseph L. Graves, who has done extensive testing of the r/K selection theory with species of Drosophila flies. …”
Genetics or culture, in dense human societies, people must devote a great deal of energy to a small number of children they can successfully raise, leading to the notion that parents are morally required to put this effort into their children. But this system is at odds with the fact that without some form of intervention, the average married couple will produce far more than two offspring.
While tromping through a blizzard, seeking insight into circum-polar peoples, I discovered a condition called chilblains. The relevant Wikipedia page is rather short:
Chilblains … is a medical condition that occurs when a predisposed individual is exposed to cold and humidity, causing tissue damage. It is often confused with frostbite and trench foot. Damage to capillary beds in the skin causes redness, itching, inflammation, and sometimes blisters. Chilblains can be reduced by keeping the feet and hands warm in cold weather, and avoiding extreme temperature changes. Chilblains can be idiopathic (spontaneous and unrelated to another disease), but may also be a manifestation of another serious medical condition that needs to be investigated.
The part they don’t mention is that it can really hurt.
The first HBD-related question I became interested in–after visiting a black friend’s house and observing that she was comfortable without the AC on, even though it was summer–is whether people from different latitudes prefer different temperatures. It seems pretty obvious: surely people from Yakutsk prefer different temperatures than people from Pakistan. It also seems easy to test: just put people in a room and give them complete control over the thermostat. And yet, I’d never heard anyone discuss the idea.
Anyway, the perfunctory Wikipedia page on chilblains mentioned nothing about racial or ethnic predisposition to the condition–even though surely the Eskimo (Inuit) who have genetic admixture from both ice-age Neanderthals and Denisovans:
“Using this method, they found two regions with a strong signal of selection: (i) one region contains the cluster of FADS genes, involved in the metabolism of unsaturated fatty acids; (ii) the other region contains WARS2 and TBX15, located on chromosome 1.” …
“TBX15 plays a role in the differentiation of brown and brite adipocytes. Brown and brite adipocytes produce heat via lipid oxidation when stimulated by cold temperatures, making TBX15 a strong candidate gene for adaptation to life in the Arctic.” …
“The Inuit DNA sequence in this region matches very well with the Denisovan genome, and it is highly differentiated from other present-day human sequences, though we can’t discard the possibility that the variant was introduced from another archaic group whose genomes we haven’t sampled yet,” Dr. Racimo said.
The scientists found that the variant is present at low-to-intermediate frequencies throughout Eurasia, and at especially high frequencies in the Inuits and Native American populations, but almost absent in Africa.
Sub-Saharan Africans have their own archaic admixture, but they have very little to no ice-age hominin–which is probably good for them, except for those who’ve moved further north.
Imagine my surprised upon searching and discovering very little research on whether chilblains disproportionately affects people of different races or ethnicities. If you were a dermatologist–or a genetically prone person–wouldn’t you want to know?
Black individuals have been shown to be 2 to 4 times more likely than individuals from other racial groups to sustain cold injuries. These differences may be due to cold weather experience, but are likely due to anthropometric and body composition differences, including less-pronounced CIVD, increased sympathetic response to cold exposure, and thinner, longer digits.3,6
While I would really prefer to have more ethnic groups included in the study, two will have to suffice. It looks like trench foot may be an equal-opportunity offender, but chilblains, frostbite, and other cold-related injuries attack black men (at least in the army) at about 4x the rate of white men, and black women 2x as often as white women (but women in the army may not endure the same conditions as men in the army.)
On a related note, while researching this post, I came across this historic reference to infectious scurvy and diabetes, in the Journal of Tropical Medicine and Hygiene, Volumes 4-5 (published in 1902):
Note: this is why it is important to discard bad theories after they’ve been disproven. Otherwise, you kill your scurvy victims by quarantining them instead of giving them oranges.
In the genomic age, it is now easy to compare the DNA of people from around the world. And it has indeed revealed that our racial categories are fuzzy proxies for genetic difference—an African man may be more closely related to an Asian than to another African.
From there, Zhang basically tries to argue that race doesn’t real even though genetics and medical science sure make it look real, that the differences in the distribution of genetic traits in large, historically isolated populations don’t matter because of a few tiny populations that are the genetic equivalent of the Basque language.
Remember, the world’s entire population of Bushmen wouldn’t even fill the Texas A&M football stadium. Combine them with a few other tiny populations, like the Khoikhoi and Pygmies, and you’re still looking at <1 million people. Meanwhile, there are billions of Europeans, west Africans, and east Asians.
Mundane racial categories work just fine for the vast majority of people, including the vast majority of Americans, who are not drawn from a rainbow of racially-mixed groups like Tuaregs or fringe outliers like the Bushmen, but from distinct populations of West Africans, Europeans (primarily NW Euros,) Native Americans, and East Asians. If I say someone is “black” or “white,” not only do you understand what I mean, there is an actually consistent genetic reality underlying my statements–in almost 100% of cases, a genetic test would in fact confirm that the people I call “black” are actually primarily Sub-Saharan African by ancestry and the people I call “white” are primarily European by ancestry. Exceptions like Rachel Dolezal are quite rare.
Zhang is trying to argue that you can’t make a reasonable argument about the average distribution of traits between whites, blacks, and Asians in the US because there is a handful of tiny, genetically isolated populations over in Africa. A does not follow from B.
On the other side of the coin, we have people who believe it’s morally imperative to only marry people from one’s own race.
Most of the time, people fall in love with people from their own culture and ethnic group. This is what we’d expect, because you’re more likely to meet and share values with people from your own group. (Interestingly, most people are more genetically similar to their spouses than they are to the average person in their community, not because they married a close relative, but because similar genes make for similar people.)
But some people, for whatever reasons, marrying within their own group isn’t a real option. (White men who are under 5’5″, for example.) These people are looking out for their own best interests–really, if you’re considering calling Derbyshire a race traitor, you’re probably thinking too much about other people’s business.
Capitalism works because it self-corrects; it allows consumers to pick the best products at the best prices, and companies to hire the most talented workers for the best wages. Unlike socialism, where companies are told what and how much to produce, consumers are told what to buy and how much it will cost, and ultimately people starve in the streets, capitalism actually works. Self-interest is a powerful organizing principle that has radically increased the welfare of billions of people over the past century.
And capitalism doesn’t care about race.
Where people live in close proximity to people of other races, some of them will fall in love.
That said, don’t date people for status points or because you’re trying to prove how not-racist you are. Like Obama’s parents, most inter-racial couples don’t stay together; the majority of mixed-race children have parents who are not married–according to one study, 92% of biracial children with black fathers are born out of wedlock and 82% end up on government assistance because their fathers do not bother to take care of them.
And if you are ever tempted to compare your vagina to the UN because of the sheer number of different ethnicities that have been in it, you need to stop and re-evaluate your life for multiple reasons.
Ultimately, real-life decisions should be based on real-life concerns.
Oh man! We are finally at part three! The part in which I attempt incorporating two-D space into our diagram:
Right, so as we turn our car around and head back up the road, we notice an intriguing turnoff in the Congolese rainforest: a tribe of the shortest people in the world, the Pygmies. According to Wikipedia:
A pygmy is a member of an ethnic group whose average height is unusually short; anthropologists define pygmy as a member of any group where adult men are on average less than 150 cm (4 feet 11 inches) tall. A member of a slightly taller group is termed “pygmoid“.
Basically, whenever humans live in tropical rainforests, there’s a good chance they’ll get shorter. (Rainforests also produce pygmy elephants.) Maybe it’s because short people can move more easily through the dense forest, or an adaptation to low levels of iodine, sunlight, or other nutrients–I don’t really know.
Wikipedia estimates that there are between 250,000 and 600,000 pygmies living in the Congo rainforest:
Genetically, the pygmies are extremely divergent from all other human populations, suggesting they have an ancient indigenous lineage. Their uniparental markers represent the most ancient divergent ones right after those typically found in Khoisan peoples. African pygmy populations possess high levels of genetic diversity, recent advances in genetics shed some light on the origins of the various pygmy groups. …
“We studied the branching history of Pygmy hunter–gatherers and agricultural populations from Africa and estimated separation times and gene flow between these populations. The model identified included the early divergence of the ancestors of Pygmy hunter–gatherers and farming populations ~60,000 years ago, followed by a split of the Pygmies’ ancestors into the Western and Eastern Pygmy groups ~20,000 years ago.”
But I recall–was it WestHunt?–objecting that the authors of this paper used a too-fast estimation of genetic mutation rates. Oh here it is:
There are a couple of recent papers on introgression from some quite divergent archaic population into Pygmies ( this also looks to be the case with Bushmen). Among other things, one of those papers discussed the time of the split between African farmers (Bantu) and Pygmies, as determined from whole-genome analysis and the mutation rate. They preferred to use the once-fashionable rate of 2.5 x 10-8 per-site per-generation (based on nothing), instead of the new pedigree-based estimate of about 1.2 x 10-8 (based on sequencing parents and child: new stuff in the kid is mutation). The old fast rate indicates that the split between Neanderthals and modern humans is much more recent than the age of early Neanderthal-looking skeletons, while the new slow rate fits the fossil record – so what’s to like about the fast rate? Thing is, using the slow rate, the split time between Pygmies and Bantu is ~300k years ago – long before any archaeological sign of behavioral modernity (however you define it) and well before the first known fossils of AMH (although that shouldn’t bother anyone, considering the raggedness of the fossil record).
Let’s split the difference and say that one way or another, Pygmies split off from their hunter-gatherer neighbors and became isolated in the rainforest quite a while ago.
Before we drive on, I’d like to pause and note that I’m not entirely comfortable with using the way Pygmies are sometimes used in racial discussions. Yes, they are short, but they otherwise look a lot like everyone else in the area. Pygmies go to school, often speak multiple languages, live in cities, work at real jobs, read books, operate businesses, drive cars, fall in love, get married, build houses, etc. For more on Pygmies see my review of Isaac Bacirongo’s memoir Still a Pygmy (Isaac is a Pygmy man who speaks, IIRC, 5 languagues, attended highschool, and owned/ran successful pharmacies in two different cities in the DRC before the army burned them down during a civil war.)
Now I admit that Isaac is just one guy and I don’t know what the rest of the Pygmies are like.
But let’s hop back in our car, for at the other end of this road we have not a small town of isolated forest-dwellers, but a large group we have so far neglected: the Native Americans.
The indigenous peoples of North and South America today number about 60 million people, plus some quantity of mixed-race people (mestizos.) In some areas these mestizos are majority European by ancestry; in others they are majority Indian; studies in Mexico, for example, estimate that 80-93% of the population is Mestizo, with Indian ancestry averaging between 31% and 66% in different regions. The people of El Salvador are about 86% mestizo; Chileans are about 40% Indian and 60% Europeans; Columbia is about 49% mestizo; etc.
Unfortunately, Wikipedia doesn’t list the total number of mestizos, and I don’t have time to calculate it, but I will note that the total population of both continents, including Canada and the USA, is about 1 billion people.
We’re not sure exactly when (or how) the Indians got here, but it looks like they arrived around 10-20,000 years ago across the then-Bering Landbridge. (I think we should also keep in mind the possibility that they could have built boats.) According to Wikipedia:
Scientific evidence links indigenous Americans to Asian peoples, specifically Siberian populations, such as the Ket, Selkup, Chukchi and Koryak peoples. Indigenous peoples of the Americas have been linked to North Asian populations by the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA. There is general agreement among anthropologists that the source populations for the migration into the Americas originated from an area somewhere east of the Yenisei River. The common occurrence of the mtDNA Haplogroups A, B, C, and D among eastern Asian and Native American populations has long been recognized. As a whole, the greatest frequency of the four Native American associated haplogroups occurs in the Altai–Baikal region of southern Siberia. Some subclades of C and D closer to the Native American subclades occur among Mongolian, Amur, Japanese, Korean, and Ainu populations.
On the grand scale of human history, (200,000 years, more or less,) 13-20,000 years is not very long, and the Native Americans have not diverged too much, physically, from their cousins in Asia. The G-allele mutation of the EDAR gene arose about 30,000 years ago somewhere in east Asia and gives both modern Asians and Native Americans (but not Europeans and Africans) their characteristic hair and skin tone. While Native Americans are clearly physically, culturally, and geographically distinct from other Asians, (just as Europeans and south-Asian Indians are distinct from each other,) they are genetically close enough that they unquestionably clade together in the greater racial schema.
As I’ve said before, my diagram is just one way to represent one aspect of the genetic (and physical) distances between people.
Here is another diagram, not mine, which tells the same story in a different way (though it estimates a much lower genetic distance between Bushmen and Bantus than I’d expect. Oh well. different studies get different results; that’s why replication and meta-analysis are super important):
The Melanesians of Papua New Guinea and Australia are in pink (there are some mixed Melanesian / Polynesian populations in the world, but our road trip skipped them.) Their nearest relatives are other south Asians and Polynesians, but those same south Asians are themselves more closely related to Europeans than Australians. Diagrammed like this, it’d be understandable to break off south Asians into one race and put Caucasians, Native Americans, and East Asians into a single race. And I suppose you could, if you wanted to and could get everyone else to start using your categories. Race is biologically real and quite obvious at the macro scale, but a few small groups like Aborigines and Bushmen introduce existential uncertainty that intellectuals can quibble over.I don’t think it would be terribly useful rearrangement, though, for all of the reasons discussed over the past three posts in this series.
Well, that’s the end of our big road trip! I hope you’ve enjoyed it, and that it’s cleared up that nagging question people seem to have: How can Nigerians be more closely related to Europeans than some other Africans? Have a great day, and enjoy the drive home.
Note: This post still contains a lot of oversimplification for the sake of explaining a few things.
Welcome back to our discussion of the geographic dispersion of humanity. On Tuesday, we discussed how two great barriers–the Sahara desert and the Himalayas + central Asian desert–have impeded human travelers over the millennia, resulting in three large, fairly well-defined groups of humans, the major races: Sub-Saharan Africans (SSA), Caucasians, and east Asians.
Of course, any astute motorist, having come to a halt at the Asian end of our highway, might observe that there is, in fact, a great deal of land in the world that we have not yet explored. So we head to the local shop and pick up a better map:
Our new map shows us navigational directions for getting to Melanesia and Australia–in ice age times, it instructs us, we can drive most of the way. If there isn’t an ice age, we’ll have to take a boat.
The people of Melanesia and Australia are related, the descendants of one of the first groups of humans to split off from the greater tribe that left Africa some 70k ago.
As the name “Melanesian” implies, they are quite dark-skinned–a result of never having ventured far from the equatorial zone.
Today, they live in eastern Indonesia, Papua New Guinea, Australia, and a smattering of smaller islands. (Notably, the Maori of New Zealand are Polynesians like the Hawaiians, not Melanesians, descendants of a different migration wave that originated in Taiwan.)
There is some speculation that they might have once been wider-spread than they currently are, or that various south-Asian tribes might be related to them, (eg, “A 2009 genetic study in India found similarities among Indian archaic populations and Aboriginal people, indicating a Southern migration route, with expanding populations from Southeast Asia migrating to Indonesia and Australia,”) but I don’t think any mainland group would today be classed as majority Melanesian by DNA.
They may also be related to the scattered tribes of similarly dark-skinned, diminutive people known as the Negritos:
Males from the Aeta people (or Agta) people of The Philippines, are of great interest to genetic, anthropological and historical researchers, as at least 83% of them belong to haplogroup K2b, in the form of its rare primary clades K2b1* and P* (a.k.a. K2b2* or P-P295*). Most Aeta males (60%) carry K-P397 (K2b1), which is otherwise uncommon in the Philippines and is strongly associated with the indigenous peoples of Melanesia and Micronesia. Basal P* is rare outside the Aeta and some other groups within Maritime South East Asia. …
A study of blood groups and proteins in the 1950s suggested that the Andamanese were more closely related to Oceanic peoples than African Pygmies. Genetic studies on Philippine Negritos, based on polymorphic blood enzymes and antigens, showed they were similar to surrounding Asian populations.
However, the Negritos are a very small set of tribes, and I am not confident that they are even significantly related to each other, rather than just some short folks living on a few scattered islands. We must leave them for another day.
The vast majority of Aborigines and Melanesians live in Australia, Papua New Guinea, and nearby islands. They resemble Africans, because they split off from the rest of the out-of-Africa crew long before the traits we now associate with “whites” and “Asians” evolved, and have since stayed near the equator, but they are most closely related to–sharing DNA with–south Asians (and Indians.)
So we have, here, on the genetic level, a funny situation. Melanesians are–relatively speaking–a small group. According to Wikipedia, thee are about 12 million Melanesians and 606,000 Aborigines. By contrast, Tokyo prefecture has 13 million people and the total Tokyo metro area has nearly 38 million. Meanwhile, the Han Chinese–not a race but a single, fairly homogenous ethnic group–number around 1.3 billion.
Of all the world’s peoples, Melanesians/Aborigines are most closely related to other Asians–but this is a distant relationship, and those same Asians are more closely related to Caucasians than to Aborigines.
As I mentioned on Tuesday, the diagram, because it is 1-dimensional, can only show the distance between two groups at a time, not all groups. The genetic distance between Caucasians and Aborigines is about 60 or 50k, while the distance between Asians and Caucasians is around 40k, but the distance between Sub-Saharan Africans and ALL non-SSAs is about 70k, whether they’re in Australia, Patagonia, or France. Our map is not designed to show this distance, only the distances between individual pairs.
Now if we hopped back in our car and zoomed back to the beginning of our trip, pausing to refuel in Lagos, we’d note another small group that has been added to the other end of the map: the Bushmen, aka the Khoi-San people. Wikipedia estimates 90,000 San and doesn’t give an estimate for the Khoi people, but their largest group, the Nama, has about 200,000 people. We’ll estimate the total, therefore, around 500,000 people, just to be safe.
The Bushmen are famous for being among the world’s last hunter-gatherers; their cousins the Khoi people are pastoralists. There were undoubtedly more of them in the past, before both Europeans and Bantus arrived in southern Africa. Some people think Bushmen look a little Asian, due to their lighter complexions than their more equatorial African cousins.
Mitochondrial DNA studies also provide evidence that the San carry high frequencies of the earliest haplogroup branches in the human mitochondrial DNA tree. This DNA is inherited only from one’s mother. The most divergent (oldest) mitochondrial haplogroup, L0d, has been identified at its highest frequencies in the southern African San groups.
In a study published in March 2011, Brenna Henn and colleagues found that the ǂKhomani San, as well as the Sandawe and Hadza peoples of Tanzania, were the most genetically diverse of any living humans studied. This high degree of genetic diversity hints at the origin of anatomically modern humans.
Recent analysis suggests that the San may have been isolated from other original ancestral groups for as much as 100,000 years and later rejoined, re-integrating the human gene pool.
A DNA study of fully sequenced genomes, published in September 2016, showed that the ancestors of today’s San hunter-gatherers began to diverge from other human populations in Africa about 200,000 years ago and were fully isolated by 100,000 years ago … 
So the total distance between Nigerians and Australian Aborogines is 70k years; the distance between Nigerians and Bushmen is at least 100k years.
When we zoom in on the big three–Sub-Saharan Africans, Caucasians, and Asians–they clade quite easily and obviously into three races. But when we add Aborigines and Bushmen, things complicate. Should we have a “race” smaller than the average American city? Or should we just lump them in with their nearest neighbors–Bushmen with Bantus and Aborigines with Asians?
I am fine with doing both, actually–but wait, I’m not done complicating matters! Tune in on Monday for more.
Note: This post contains a lot of oversimplification for the sake of explaining a few things. (Yes, I am still meditating on the greater Asian clade.)
Imagine you’re driving down a long highway that stretches from Nigeria to Beijing, passing through Berlin and New Delhi. In reality this route takes some large twists and turns, but we’re drawing it as a straight line, for all maps must simplify to be useful.
As you drive along, you pass many houses along the way–sometimes just a few clustered next to the highway, sometimes small towns, sometimes megalopolises with billions of people.
Our drive begins in one such megalopolis, that of Sub-Saharan Africa (SSA.) Here we meet people like Queen Anna Nzinga, author Chinua Achebe, and–though they have traveled far abroad–African Americans like Oprah Winfrey and Martin Luther King.
Though thousands of different languages are spoken by the thousands of different groups throughout SSA, we may still note a certain physical similarity among them–dark skin perfectly adapted to the equator’s strong sun, dark eyes, and tightly curling hair. While there is a tremendous amount of variety here–probably the most of any megalopolis in the world–they are also, quite clearly, related. You don’t have to go measuring skulls to figure that out.
But as we drive north, the houses thin out. Suddenly we are in a zone with almost no people–an enormous desert: the Sahara.
We speed through this harsh, empty landscape on a starry night, spotting only a few camels in the distance. We’re lucky we have a full tank of gas and several more in the trunk–for all but the most intrepid of our pre-automobile ancestors, this desert was nigh impassible, a vast barrier to human movement.
Finally we reach the vast inland sea of the Mediterranean, and the beginning of our second megalopolis. Most of the people here, from Berbers to Egyptians, have their own distinct look, more similar to their neighbors from the Middle East and Southern Europe than their neighbors to the south, across the inhospitable expanse of sand.
While there are many different countries and languages, no clear phenotypic line separates the people of Northern Africa, the Middle East, southern Europe, or northern Europe. Skin pales, hair lightens and becomes wavy, eyes turn a variety of hues as one nationality melts into the next. North-central Europe is the only place in the world where blue/green/hazel eyes and blond hair are common in adults; even in Wales, dark hair is dominant.
We hang a right through Turkey, Iran, Pakistan, and India, teeming with people. Here again, though the people change and there are barriers like the Thar Desert, we find no harsh, nigh-impenetarable breaks like the Sahara.
Then, suddenly, we run smack into a wall, a natural wall of majestic proportions: the Himalayas. Beyond lie the Tibetan Plateau, Gobi Desert, and the vast emptiness of the Asian steppe. If this land was ever densely populated, generations of marauding steppe warriors have wiped them out. We see a few people here–aptly named Tibetan lamas, flocks of sheep grazing beside a scattering of yurts. Mongolia holds the distinction of being the world’s least densely populated independent country. (Ice-covered Greenland is even less dense, but owned by Denmark.)
Finally we pass beyond the shadow of the Great Khan’s memorial and into the valley of the Yellow River, where we find our third megalopolis: east Asia.
There is notably less genetic diversity here than in the first megalopolis–indeed, 93% of Han Chinese share a particular variety of the EDAR allele:
A derived G-allele point mutation (SNP) with pleiotropic effects in EDAR, 370A or rs3827760, found in most modern East Asians and Native Americans but not common in African or European populations, is thought to be one of the key genes responsible for a number of differences between these populations, including the thicker hair, more numerous sweat glands, smaller breasts, and dentition characteristic of East Asians. … The 370A mutation arose in humans approximately 30,000 years ago, and now is found in 93% of Han Chinese and in the majority of people in nearby Asian populations.
Here, too, skin tones vary from north to south, though not as greatly as they do closer to the Greenwich Meridian. Most people have dark eyes, slim frames, and straight, smooth black hair.
Here in the megalopolis made famous by Beijing, Shanghai, Hong Kong, Seoul, and Tokyo, we have come to the end of the–first round–of our journey. From Africa to Asia, we have found three vast areas filled with people, and two major barriers which–though not completely impassible–have hindered humanity’s footsteps over the millennia.
People sometimes try to claim that human races do not exist simply because edge cases exist, small, scattered groups which possess a mixture of genes common to both Sub-Saharan Africans and Caucasians, Caucasians and Asians. And these groups do in fact exist, and are fascinating in their own rights. But these groups are also small, often living in extremely harsh, forbidding lands where few humans can survive (The inhabitants of the Himalayas and Tibetan plateau, I note, actually carry a gene that helps them survive at high altitudes which they received via an ancestor’s dalliance with a Denisovan hominin–the Denisovans were cousin to the Neanderthals and lived in Asia long before Homo Sapiens. No one else in the world carries this gene, so if you don’t have it, good luck living up there!)
But the vast, vast majority of the world’s people do not live in these harsh and unforgiving lands. They live clustered together in the enormous population centers, continually mixing, migrating, churning, and conquering each other, not people thousands of miles off. The concept of race stems from this basic observation of the geography of human settlements.
Physical distance is genetic distance, but since my diagram is only two-dimensional, it can only show the genetic distance between two points at a time. The genetic distance between Asians and Caucasians is about 40k years–much shorter than the distance between Sub-Saharan Africans and Caucasians, 70k years. But the distance between Sub-Saharan Africans and Asians is also about 70k years. Although Asians and Caucasians split apart from each other about 40,000 years ago, they are both descended from a single group of ancestors (a handful of Denisovans and Neanderthals excluded) who left sub-Saharan Africa about 70k years ago. We may best think of the relationship between these three groups not as a single highway, but as a triangle with two sides 70k long and one side of 40k. But to accurately add more groups to our journey, (as we shall do on Thursday), we would have to keep adding dimensions, and we are aiming here for simplicity, not n-dimensional hypercubes.
